I am developing the SharePoint site for the finance team at our company. One of the requirements is that we have "distribution lists" so that when a user clicks on a link, it automatically opens Outlook with the "To:" field populated with all the team members names for a certain group. One of the groups would be the "Finance Leadership Team."

Example scenario:

A finance employee has a document that she just completed. After completing the document, she must send it to all employees that are a part of the finance leadership team. She accesses the finance SharePoint site, clicks a link that opens Outlook and fills in the "To:" field with all members of the finance leadership team, attaches the file and a message, and clicks send to distribute the document to the team.
